Practise eco-driving
Source: https://www.theguardian.com/
Research by the RAC Foundation has found that eco-driving leads to safer, cleaner and more affordable journeys. Regular vehicle maintenance improves fuel efficiency by as much as 10%. Before a long journey, check tyre pressures (tyres underinflated by a quar can cause a 2% increase in fuel consumption), remove unused roof racks and boxes, and don’t overload the car (every additional 45kg reduces fuel economy by 2%). At less than 40mph, it’s more fuel-efficient to open a window than use air conditioning. Turn off engines for waits of more than one minute (5-8% of fuel is composed while idling), and avoid sharp acceleration and heavy braking: aggressive driving can significantly raise fuel consumption.
